Mega Hybrid
Posted: Sun Oct 15, 2006 8:29 pm
Hi all.
I'm new here as you can see, but that does not mean I'm new to spud gunning.
I am currently gathering parts for a huge hybrid and almost ready for constuction. Here are the parts I have:
2 foot long sch 80 8 inch steel pipe (chamber)
8 foot long steel pop can barrel (seriously, pop cans fit perfectly)
8hp gas motor
1/2 inch thick steel plate
misc. pipe fittings
I plan to cut six to eight holes in the steel plate via blowtoch, so the plate can be bolted to the chamber. Pieces of angle iron will be welded to the side of the chamber for the nut to hold on. Thy reason why I don't just weld the plate to the chamber is there is no way I can get an airtight weld. with the plates as endcaps I will then proceed to the barrel. The barrel will be on a hinge for easy burst disk placement. It will have a bolt to secure it in place for firing. I will have a standard propane meter mounte on the side. With the basics done I will move on to the hard part, the motor. The motor will be for turning an old air compressor piston mounted right on the gun. I am hoping that i will be able to get up to 300 psi fuel- air mix with this setup. No more running to the air compressor for each shot.
I have one problem though, ignition
I cannot obtain a stungun where I live and want multiple sparks so a bbq ignitor won't work (i think)
